Maternal antibodies contribute to the protection of young infants from infectious diseases during the early life. However, vaccinations for women of child-bearing age are not routine in China. Therefore, we investigated the level of protective immunity against vaccine preventable diseases in pregnant women and newborns in China. A total of 194 paired maternal and cord blood samples were collected in Beijing from 2016 to 2017. Antibodies specific for the antigens covered by diphtheria-tetanus-pertussis (DTP) and measles-mumps-rubella (MMR) vaccine were determined by ELISA (Euroimmun, Lübeck, Germany). The cut off value of ≥0.1 IU/ml (anti-diphtheria), >0.1 IU/ml (anti-tetanus), >40 IU/ml (anti-pertussis toxin), ≥200 IU/l (anti-measles), ≥45 RU/ml (anti-mumps) and ≥10 IU/ml (anti-rubella) were used to assess the percentage of newborns with protective IgG concentrations, respectively. The results revealed that 61.3%, 73.2%, 97.4%, 30.4%, 65.5% and 17.0% of newborns had no protection against diphtheria, tetanus, pertussis, measles, mumps and rubella. Only 1.0% and 23.7% of newborns had protection against all three components of DTP or MMR, respectively. The finding suggested that most of newborns were susceptible to diphtheria, tetanus, pertussis and mumps, almost one-third of this population had no immune protection against measles, and about one-sixth of them were under threat of rubella infection. These data supported the immunization program for DTP and MMR vaccine in women at child-bearing age.
母体抗体有助于保护婴幼儿免受生命早期的传染病的侵害。然而，在中国，针对育龄妇女的疫苗接种并不是常规的。因此，我们调查了中国孕妇和新生儿对疫苗可预防疾病的保护性免疫水平。2016 年至 2017 年，我们在北京共采集了 194 对母婴配对的母血和脐血样本。采用酶联免疫吸附试验（Euroimmun，吕贝克，德国）检测针对白喉-破伤风-百日咳（DTP）和麻疹-腮腺炎-风疹（MMR）疫苗抗原的特异性抗体。采用≥0.1 IU/ml（抗白喉）、>0.1 IU/ml（抗破伤风）、>40 IU/ml（抗百日咳毒素）、≥200 IU/l（抗麻疹）、≥45 RU/ml（抗腮腺炎）和≥10 IU/ml（抗风疹）的截断值来评估新生儿保护性 IgG 浓度的百分比。结果显示，61.3%、73.2%、97.4%、30.4%、65.5%和 17.0%的新生儿对白喉、破伤风、百日咳、麻疹、腮腺炎和风疹无保护作用。只有 1.0%和 23.7%的新生儿对 DTP 或 MMR 的三种成分均有保护作用。结果表明，大多数新生儿易感染白喉、破伤风、百日咳和腮腺炎，近三分之一的人群对麻疹无免疫保护作用，约六分之一的人面临风疹感染的威胁。这些数据支持对育龄妇女进行 DTP 和 MMR 疫苗的免疫接种计划。
